Vilanterol acetate
Based on 6 publication(s) in Google Scholar
Vilanterol (GW642444) acetate is a long-acting β2 adrenergic receptor agonist. Vilanterol acetate has pEC50 values for β2-AR, β1-AR, and β3-AR of 9.4, 6.4, and 6.1, respectively. Vilanterol acetate selectively activates airway β2 adrenergic receptors, increases cAMP and thus relaxes bronchial smooth muscle. Vilanterol acetate can be used in asthma research[1][2].

Biological Activity
Vilanterol acetate (Compound 13f) is a highly efficient (β2: pEC50 = 9.4), highly active (IA = 0.69), and highly selective (pEC50 difference: β2/β1 = 3.0) β₂ receptor agonist in CHO cells transfected with human β1, β2, and β3 receptors[1].
Vilanterol acetate (5 μM, 30 min) undergoes rapid metabolic inactivation in the systemic circulation during human liver microsome experiments[1].
Vilanterol acetate has moderate membrane permeability in MDCKII-MDR1 cells (P_app = 34 nm/s), which may reduce systemic absorption[1].
Vilanterol acetate is highly selective for β2-AR, with at least 1000-fold selectivity for the β2-AR and β3-AR subtypes[2].

The objective of the next set of experiments is to determine if the (i) super long-acting 2-AR agonists Indacaterol and Vilanterol inhibit TNF-α in a β-arrestin2-dependent manner, and (ii) whether β-arrestin2 is involved in the anti-inflammatory conversion leading to the up-regulation of IL-10 production by these β2-AR agonists.
